[ovirt-users] Query about running ovirt-4.2.1 engine support 3.x nodes ?

[Joseph Kelly]

Sorry to ask again, But I can see from the link below the that nodes and engines should work between minor number

upgrades. But is ovirt 4.2.x backward compatible with, say, 3.6 nodes. Does anyone know ? Is this documented  anywhere ?

Hello All,


I have two hopefully easy questions regarding an ovirt-4.2.1 engine support and 3.x nodes ?


1) Does an ovirt-4.2.x engine support 3.x nodes ? As This page states:


"The cluster compatibility is set according to the version of the least capable host operating system in the cluster."


https://www.ovirt.org/documentation/upgrade-guide/chap-Post-Upgrade_Tasks/


Which seems to indicate that you can run say a 4.2.1 engine with lower version nodes, but is that correct ?


2) And can you just upgrade the nodes directly from 3.x to 4.2.x as per these steps ?


1. Move the node to maintenance
2. Add 4.2.x repos
3. yum update
4. reboot
5. Activate (exit maintenance)


I've looked in the release notes but wasn't able to find much detail on ovirt-nodes upgrades.


Thanks,

Joe.
